The article states:

Like UDP, IPX is a datagram protocol used for connectionless communications.
SPX is a transport layer protocol (layer 4 of the OSI Model) used in Novell Netware
networks. The SPX layer sits on top of the IPX layer (layer 3 - the network layer) and
provides connection-oriented services between two nodes on the network.
IPX and SPX both provide connection services similar to TCP/IP, with the IPX protocol
having similarities to IP, and SPX having similarities to TCP.

The first entry conflicts with the two latter and is probably in error. I'm assuming that it should say, "Like IP, IPX is a packet protocol..." or, "Like UDP, SPX is a datagram protocol...". I know virtually nothing about IPX/SPX, but I know that UDP is a multiplexing datagram service and that IP deals with packets. I assume from its name that SPX operates like a sequenced version of UDP instead of a streaming model like TCP. Can anyone shed some light here? --Heywood 19:30, 11 July 2006 (UTC)

However, if IPX can multiplex ports like UDP (effectively serving unsequenced datagrams by itself), the second snippet should specify this, since it would act like both a layer 3 and layer 4 protocol. --Heywood 19:40, 11 July 2006 (UTC)

Comparison =[edit]

The comparison is great lets you know what something is like but in this case it only holds back from what SPX really is. Sequenced packet Exchange (SPX) The packets are sent with a numbering system just like TCP so they can be rearranged on the receiving end Just like TCP. Making for a more reliable connection. But Once again I got my info from a book Written by J. L. Antonakos and H. C. Mansfield Jr. read my post under IPX Discussion

Change to "Split Tunnel"..... or elimitate since this is true with all other possiable protocols.

One area where IPX remains useful is to sidestep VPN (client software that does not allow Split tunnel) that force all TCP/IP traffic to traverse the VPN, preventing any access to local resources such as printers and shared disks (on the same lan while connected to the vpn).

A.hawrylyshen (talk) 01:23, 15 December 2007 (UTC) Agreed- that IPX is able to avoid forced routes with VPN software is not a feature of IPX, but a feature of a non-IP protocol. This claim in overly aggressive

Comparing protocols[edit]

IPX can be compared to UDP; SPX can be compared to TCP; neither of them can be compared to IP; SPX is implemented on top of IPX, like TCP isn't implemented on top of UDP NevemTeve (talk) 13:35, 5 April 2015 (UTC)

Merge IPX/SPX with IPX[edit]

Disagree. IPX is a transport layer (and network layer) protocol, while IPX/SPX is a protocol family. The proposal is almost equivalent to a proposal to merge Internet protocol suite with Internet Protocol. Kolarp (talk) 12:20, 11 October 2017 (UTC)
